This is typical for OPCAB and can be explained by "enucleation" of the heart, kinking of vessels, reduction of venous return, and impairment of ventricular geometry [ 1, 19].
A lot of investigations have also focused on influence of vessel speed reduction on emissions but since that is not a solution for NOx Tier III compliance it is not dealt with in this paper.
This paper investigates the success of the Vessel Speed Reduction Program at the Ports of Los Angeles and Long Beach and uses qualitative methods to analyze the factors that contributed to the success of the program at reducing local air quality pollutants.
The changes of the 3D rendered functional microvasculature were shown in Fig. 5, where the functional vessel density reduction could be observed directly after renal ischemia.
Accelerated vascular smooth muscle cell (VSMC) proliferation is implied in cardiovascular disease and significantly contributes to vessel lumen reduction following surgical interventions such as percutaneous transluminal coronary angioplasty or bypass surgery.
In this way, the proposed algorithm enables unique visualization of choroidal watershed zones, as well as the vessel size reduction when investigating the choroid from the sclera towards the retinal pigment epithelium (RPE).
'Functional' rarefaction is defined as a decrease in the number of perfused vessels without reduction of the number of vessels anatomically present; whereas, 'structural' rarefaction refers to an actual reduction in the number of anatomically present vessels in the tissue [ 10].
When using molecular targeted drugs, downregulation of VEGF, normalisation of the tumour vasculature, pruning of excess vessels and reduction of interstitial fluid pressure and vessel permeability occur in the tumour consecutively [24, 25, 26, 27, 28, 29].
Keeping the maximum response at each pixel allows for enhanced contrast of the vessels and reduction of background noise.
Several mechanisms have been proposed including increased blood flow through capillary vessels, oedema reduction and mechanical stretching of cells leading to cell growth and expansion [ 26, 27].
